Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for feeding small fish onto a steamer with a uniform thickness.

[Prior Art] In the process of processing small fish, such as boiling and drying dried sardines, sardines, whitebait crepe, etc., the process of supplying small fish uniformly and thinly to a steamer or a net conveyor is often carried out.

As shown in FIG. 1, a water steamer has a square or rectangular frame 1 made of wooden blocks, etc., and a sheet-like net 2 stretched over the bottom to prevent small fish from falling into it. small fish,
Wash it to remove scales, slime, etc., spread it evenly on a steamer, assemble ten or more steamers 3 on an assembly stand as shown in Figure 2, and boil them all at once in a boiling pot. The boiled material is spread out one by one again and dried in the sun,
Transfer to drying duct and dry.

At present, feeding small fish into a steamer in a uniformly thin manner as described above is generally done almost manually.

Figure 2 shows the process of manually leveling small fish on a bamboo steamer. First, a steamer 3 is placed on the solo pan chute 4, and a required amount of small fish from a fish tank is scooped up with a net and supplied onto the steamer 3. Hold this bamboo steamer 3 in your hand and move it up and down several times while tilting it up and down and diagonally using the water surface of the cleaning tank as a boundary to even out the small fish. This work involves cleaning and leveling the small fish uniformly, but it requires considerable skill to level the small fish uniformly and without spots, and it requires a lot of work as it is usually done by two people facing each other. It had the disadvantage of being labor intensive.

[Purpose] The present invention is configured so that small fish can be evenly leveled on a steamer and washed in this process, so that the small fish can be evenly spread, evenly, and more efficiently with greater accuracy than manual labor. To provide a device for uniformly feeding small fish arranged in rows.

[composition] Embodiments of the present invention will be described below based on the drawings.

The apparatus shown in FIG. 3 that uniformly supplies small fish to a steamer is equipped with a supply means for supplying a fixed amount of small fish per unit time, a supply means for sending the small fish together with dispersion water to the steamer 17, and a supply means for supplying dispersion water to the supply means. It is equipped with a water supply means 7 and a conveyor 8 for moving a steamer 17 that receives small fish and dispersed water sent out from the supply means.

The supply means consists of a fish feeder 5 and a supply duct 6,
The fish feeder 5 includes a fish pump 9, a sorter 10 for sorting small fish transferred together with water from the fish tank by the fish pump 9 and separating them from the water, and a sorter 10 that is delivered below the sorter 10. and a net conveyor 11 for transporting small fish in fixed amounts.

The sorting machine 10 uses grid materials 12U and 12D for sorting large and small fish.
are stretched in a double sloping manner, and the small fish pass through the upper grid 12U, slide on the lower grid 12D, and fall onto the net conveyor 11. Large fish do not pass through the upper grid and are removed to the upper grid 12U. Upper and lower grids 12U, 12D
A tank 13 is provided below the grids 12U and 12D to remove water that has flowed down.

A drainage tank 14 is provided below the net conveyor 11, and water flowing down from the net conveyor 11 is removed from the drainage tank 14. The net conveyor 11 is operated in synchronization with the movement of the steamer. Small fish are sent to the supply duct 6 only when the net conveyor 11 is operated. If the operating speed of the net conveyor 11 is increased, the amount of small fish sent out will increase. In order to more accurately quantify the amount of small fish sent out by the net conveyor 11 per unit time, a control member 15 is disposed above the net of the net conveyor 11, as shown in FIG.

The control member 15 is preferably vertically movable,
The lower edge is always held horizontally, and the distance between the net conveyor 11 and the top surface of the net is adjusted.

The closer the distance between the lower edge of the control member 15 and the upper surface of the net of the net conveyor is, the smaller the amount of small fish delivered per unit time is.

The control member 15, which moves up and down to limit the amount of small fish sent out from the net conveyor 11, detects the amount of small fish placed on the net conveyor 11 with a fish sensor 16, and uses the fish sensor 16 to control the fish pump. Controls the operation of 9. The fish sensor 16 issues a signal to operate the fish pump 9 when the amount of small fish on the net conveyor 1 falls below a predetermined value, and issues a stop signal to the fish pump 9 when the amount of small fish exceeds a predetermined value.

The supply duct 6 is shown in FIGS. 3-4.

This supply duct 6 sends small fish fed from the fish feeder 5 onto the steamer 17 together with dispersion water. The supply duct 6 includes an upper-opening hopper 18 for receiving small fish sent from the fish feeder 5, and an expanding duct part extending horizontally from the hopper 18 and increasing in width in the direction of small fish transfer. 19, and a supply port 20 is opened downward at the end portion of the expanding duct portion 19, which is widened in width.

The supply duct 6 has a water supply port 21 opened on the opposite side of the expanding duct portion 19 so that the small fish are transported by being carried away by the dispersed water. The water supply port 21 is connected to the water pump 2 which is the water supply means 7.
Small fish are flown along the expanding duct part 19 by the dispersion water sent from here.

As shown in FIG. 4, the expansion duct portion 19 has side walls 2 on both sides.
3 and is open at the top.

The supply port 20 is opened downward, as shown in FIG. 3, so that the small fish placed on the steamer 17 are not swept along the steamer more than necessary by the dispersed water flowing out from here. , as shown in FIG. 4, the direction of the conveyor 8's width (lateral direction in FIG. 4)
It has a wide shape with a large dimension in the vertical direction (in FIG. 4) and is opened downward.

The water supply means 7 supplies dispersed water to the supply duct 6 to loosen the small fish supplied in a lump, and transfer the small fish to the expanded duct section 1.
9, the small fish are fed to the supply port 20 while being uniformly dispersed, and the small fish are allowed to fall smoothly and uniformly onto the steamer 17, and are evenly distributed on the steamer 17. Therefore, the most preferable position for the water supply means 7 to supply water to the supply duct 6 is the hopper 1 of the supply duct 6, as shown in FIG.
8 and is on the opposite side of the expanding duct portion 19. However, although not shown, the water supply means can also supply dispersed water from the expanding duct part of the supply duct to the preceding process or near the delivery part of the net conveyor that is the fish feeder.

The discharge amount of the water pump 22, which is the water supply means 7, is determined to be an amount that allows the small fish fed into the hopper 18 of the supply duct 6 to flow smoothly and to be uniformly distributed on the steamer 17.

The water pump 22 is operated even when the net conveyor 11 of the fish feeder is stopped.

The steamer 17 has a net 2 stretched over a rectangular frame 1, and small fish are uniformly placed on the steamer 17 while being transported by a conveyor 8.

The conveyor 8 in FIG. 3 is a lobe conveyor, in which a pulley 24 is driven by a motor, a lobe 25 is hung on the pulley 24, and a steamer 17 placed on a row 125 is moved.

A steamer sensor 26 is provided on the lobe conveyor to detect the presence or absence of the steamer 17 below the supply port 20. The steamer sensor 26 controls the operation of the net conveyor 11 of the fish feeder 5.

The net conveyor 11 of the fish feeder is operated only when the steamer sensor 26 detects that there is a steamer below the supply port 20, and when there is no steamer 3 below the supply port 20, the operation of the net conveyor 11 is stopped. . Even after the net container 11 of the fish feeder stops operating, the small fish that were in the supply duct 6 are sent onto the steamer 3.

That is, there is a time delay between the operation of the net conveyor 11 and the feeding of small fish from the fish feeder 5. This time delay is corrected by the mounting position of the steamer sensor 26. To be more precise, the steamer sensor 26 is disposed at a position moved to the left in FIG. 3 from the supply port 20.

A steamer with the most suitable shape is used depending on the purpose. Therefore, the present invention does not limit the shape of the steamer.

Seiros are stacked each as a single unit,
Or you can line them up to dry.

The small fish are washed by the dispersion water when they are evenly placed on the bamboo steamer 17. When it is necessary to clean the scales attached to the small fish on the steamer 17, as shown in Figures 3 and 5, spray water upwards below the steamer 17 on which the small fish are placed. A cleaning nozzle 30 may be provided.

The cleaning nozzle 30 cleans the scales adhering to the underside of the small fish and causes them to fall off.

The width of the cleaning nozzle 30 increases upward as shown in FIG. 5 so that cleaning water can be uniformly sprayed over the entire width of the steamer 17 on which small fish are placed.

The flow rate of the cleaning water sprayed by the cleaning nozzle 30 is
It is best to set the position so that the small fish on the top do not jump up.

Below the steamer 17 and below the supply port 20, the steamer 1
A drainage receiver 31 is provided to receive the dispersed water flowing down through the drainage receiver 7, and a drainage port 32 is opened in the drainage receiver 31.

[Operation] Hereinafter, the operation of the apparatus configured as described above for uniformly feeding small fish to the steamer will be explained in the order of each member.

■ Dispersed water continuously fed into the supply duct 6 from the water supply means 7 passes through the expanding duct part 19 of the supply duct 6 to the fourth
It is spread uniformly in the direction shown by the arrow in the figure and dropped from the supply port 20.

■ In this state, when the steamer sensor 26 detects the steamer 17 sent on the rope conveyor 8, the net conveyor 11 is operated for a certain period of time, and the small fish are supplied to the supply duct 6 along with water. Expansion duct part 1
It is spread uniformly at 9 and dropped from the supply port 20.

■ In this case, the position of the steamer sensor 26 is
is detected in front of the supply port 20, the net conveyor 11 is started, and the time when the small fish are carried to the supply port 20 by running water must be timed to match the time when the steamer 17 reaches the supply port 20. . Therefore, the timing of stopping the net conveyor 11 is also determined when the basket 17 is at the supply port 2.
Must stop before passing 0.

(2) Since the flow rate of the expanding duct 19 is constant, the water is expanded very efficiently and filled into the steamer 17.

(2) The layer thickness of the small fish filled on the bamboo steamer 17 can be adjusted by moving the control member 15 up and down, but it is also possible by adjusting the rotation speed of the net conveyor 11.

■ The scales on small fish such as sardines are washed and separated by running water and fall into the steamer 17, where the small fish remain on the mesh of the steamer I7, but the rust passes through the mesh of the steamer along with water into the drainage receiver 3.
1 and is discharged from the drain port 32.

- The amount of water dispersed in the expansion duct portion 19 is preferably larger than the amount of small fish to be supplied. According to experiments conducted by the present inventor, it takes several hundred seven minutes to 1m37 minutes to fill a 1rn2 square steamer with approximately 3kg of sardines. A pump with a large head and flow rate is suitable, and the feeding speed of the steamer is 30 pieces/minute, and for 30 pieces x 3 kg = 90 kg of sardines,
The water ratio was 500-1000. The weight ratio of dispersed water to small fish was 18 to 9%. If the flow rate of the dispersed water is small = 12-, the water surface level in the supply duct 6 will drop, and small fish will not flow smoothly through the expansion duct section 19.

■ The thickness of the layer of small fish filled on the bamboo steamer 17 can also be adjusted by making the traveling speed of the lobe conveyor variable. The fish is conditioned.

(2) If the control member 15 of the net conveyor 11 is lowered too much when the fish is large, the fish may become clogged and cannot be discharged smoothly. Therefore, in this case, it is better to lower the rotation speed of the net conveyor 11 than to lower the control member.

[Phase] Some of the small fish supplied to the steamer 17 have scales etc. attached to the back side thereof. The scales can be removed by blowing up a water stream from the bottom to the top using a cleaning nozzle 30 that matches the width of the steamer. As shown in FIG. 3, the cleaning nozzle 30 is preferably inclined in a direction midway between the traveling direction of the steamer 3 and the vertical direction. This is because vertically upwards, the last small fish in the bamboo steamer may spill in the opposite direction of the steamer's progress.

■ The load of the lobe conveyor is enough to support and transport the weight of the steamer 17 and small fish, so the width of the steamer is approximately 1000 mm.
Compared to the above, four ropes with a diameter of 10 mm are used, and the cross section thereof is shown in FIG. 5. The washing water from the washing nozzle 30 has thin and rough lobes, so it does not interfere with washing the steamer.

■ Groundwater, seawater, etc. are supplied to the supply port 21 of the supply duct 6, but when drying immediately at low temperatures using cold air drying, etc., cold water is used, and the cold water is filtered to remove foreign substances such as scales. It is best to remove it and recirculate it for repeated use.

[Effects] In the present invention, a supply means for mixing water and small fish and supplying small fish intermittently at a uniform speed is disposed above the conveyor, and a flexible wire such as a lobe is placed below the supply means. A plurality of conveyors are connected in an endless ring shape and extend horizontally, and on this conveyor, a steamer with a porous net lined inside is placed. The structure is such that small fish are uniformly supplied from the supply port onto the steamer from the supply means along with water for uniformly leveling the small fish by a signal from a detection sensor that detects the approach of the steamer while moving toward the end.

When this device drops a small fish containing a large amount of water onto a moving cellar from an upper feed port, the large amount of water will be sucked into the numerous openings in the porous mesh material of the cellar. In addition, it is evened out in the plane direction without scattering on the steamer, and is supplied with a uniform layer thickness. To explain the above action in more detail, a large amount of water and small fish are fed through the supply port, which is wider in the direction perpendicular to the direction of conveyor movement, that is, in the horizontal direction, than in the vertical direction. When water is supplied, small fish are momentarily suspended in the water by a large amount of water on top of the steamer, and the water flows down through the openings in the porous mesh material of the steamer, but they are closed by the small fish first. The water does not flow into the opened opening, but instead moves toward the unblocked opening, and along with the water, the small fish move to the opening and block it. Therefore, the small fish are carried along with the water from the thicker layer to the thinner layer, and the layer thickness of the small fish on the steamer becomes uniform (similar to the principle of paper making). As the steamer moves on the conveyor, it is fed from one end of the steamer in a wide and linear manner through a wide supply port in the width direction, and is supplied as a surface in the direction of travel of the conveyor as well as the direction of travel of the steamer.

Furthermore, water passing between small fish and the porous mesh material of the steamer,
It also has the effect of cleaning small fish, and in addition to being evenly dispersed by the water, the small fish are also washed, and the small fish on the steamer are well-washed and evenly arranged on the steamer. .

Furthermore, the conveyor for transporting the steamer has a plurality of flexible wires stretched on the same plane, and the steamer is placed on the wires and transported. Therefore, the conveyor does not impede water permeation through the steamer, and water permeates uniformly throughout the porous net material, thereby minimizing uneven distribution of small fish caused by non-uniformity of permeated water. This is because, as mentioned earlier, the device of the present invention allows water to pass through the parts of the bamboo steamer that are not blocked by small fish, so that the parts of the bamboo steamer that are not blocked by small fish can be blocked by small fish.
In other words, small fish are carried to areas where there are few small fish and distributed evenly, but even though there are no small fish, if the bottom of the netting material or the conveyor is blocked and the amount of permeated water decreases, this area Small fish are not transported sufficiently and small fish are distributed unevenly, but the wire rod has a small contact area with the bottom surface of the net material, reducing the area where small fish are supplied and causing uneven distribution area of small fish. It is possible to realize features that can reduce the amount of

Furthermore, small fish have soft bodies and easily get injured on their abdomens, but since they are fed together with water into the steamer from the feed port at a low head, uniform feeding can be achieved without damaging the small fish.
